Precision Coded Analytical Performance
- Coded Element Recognition: Specifically designed with internal coding for automatic element recognition by compatible Agilent, Varian, and GBC Scientific AAS instruments.
- High-Intensity Gold Cathode: Constructed using premium Gold (Au) for ultra-stable spectral output and high signal-to-noise ratios, essential for trace analysis.
- Optimal UV Transmission: Features a high-quality quartz window to ensure maximum transmission of the 242.8 nm Gold resonance line.
Advanced Connectivity & Fitment
- Industry Standard 37mm (1.5"): The standard 1.5-inch diameter housing ensures a perfect fit into the lamp turret of most modern Atomic Absorption Spectrometers.
- Four (4) Pin Coded Base: Equipped with a robust 4-pin base configuration required for instrument-specific coding and automated setup.
- Varian & GBC Compatibility: Engineered to meet the technical requirements for seamless integration with Varian and GBC Scientific AAS systems.
Validated Spectral Output
- Primary Analytical Line: Optimized for high-sensitivity determination at the 242.8 nm primary wavelength.
- Alternative Wavelength Support: Provides reliable spectral emission at 267.6 nm for higher concentration samples where reduced sensitivity is preferred.
- Rigorous Quality Control: Every Photron lamp is individually tested to verify strike voltage and operational stability before shipment.
